On Monday, the Forest Preserve tweeted that it was aware of the June 14 incident at an undisclosed park location and video.
Irizarry's brother intervened to stop the man from following her. "You know that right?" the harassing officer added referring to the woman's shirt. The world is not going to change the United States of America.
"You should not be wearing that in the United States of America", the man tells her.
The man continued to criticize her, even as more cops arrived, saying, "You're not American, if you were American you wouldn't wear that".
Ironically, the initial officer wound up taking the official report from Irizarry, who pointed out that she asked for his assistance multiple times. The officer is seen turning the other way. Can you please grab him?More news: Kylie Jenner Says Baby Stormi Gets Her Lips from Travis Scott!
"Well I guess you just never know", Irizarry responds. In the video, the woman can be heard asking the officer, "I do not feel comfortable with him here; is there anything you can do?"
The man was placed under arrest and charged with assault and disorderly conduct.
"All people are welcome in the Forest Preserves of Cook County, and no one should feel unsafe while visiting our preserves".
Irizarry recorded the exchange in a Facebook Live video that has since been viewed more than 1.4 million times and drawn outcry from local leaders, members of Congress and the Puerto Rican governor himself.
"'Is she an American citizen?" he then asks the officer.
Preckwinkle called the video "completely unacceptable" and said she was "troubled" by the officer's response to the "terrible" incident. "People have just as much right to be here as you do, and when you're drunk you don't belong here".More news: Samsung to launch Galaxy S10 Plus with five cameras
Rossello Tweeted: "I am sure @tonipreckwinkle will take matter into her hands as justice and diversity have been central to her exemplary career".
"In this case, a USA citizen questions the citizenship of another United States citizen and American law-enforcement just sits back and watches", he said.
Puerto Rico was hit by a devastating storm, Hurricane Maria, last September. Puerto Ricans are American citizens whether they are born on the US mainland or in Puerto Rico and have been since 1899, when Puerto Rico was acquired as a territory.
Stagner confirmed that the man who was shown harassing Irizarry was charged by the preserve's police department. Those born there are US citizens, although they can not vote in USA presidential elections.
Stagner and the Forest Preserves are not the only ones upset by the video, as Puerto Rican Gov. Ricardo Rossello tweeted about the "undignified event", calling the man a bigot and finding fault with the first officer who "did not interfere".More news: Section 377 Hearing in Supreme Court
